I'm 40 years old, married for 18 years. We have kids (14 and 11). I'm self-employed. My wife works full-time and is finishing her 4-year degree. Like you all, we're very busy. Many times she bites her lip as I head out the door to ride while the grass needs cutting, rooms need painting or one of the kids needs a ride to the orthodontist. Without her support there would be no cycling for me. She's wonderfully tolerant of my obsessions, and I, in return, try to find a balance among home, work, family, church, and the bike (there may be more).
However, one day last year she gave me some grief about my riding and I told her that most guys my age had a girlfriend and a Corvette and that cycling, maybe, wasn't so bad.
